This invention comprises novel and useful improvements in a stri ng machine and more specifically pertains to an attachment which may be applied to trucks for striping or marking tra-ific lanes of highways from the moving truck.

The principal Object of this invention consists in providing an apparatus which shall capable ofsimultaneously'striping'or painting lane markers for a plurality of traflic lanes iron; a moving truck.

'An additional purpose of the invention is to provide an apparatus in conformity with the foregoing object, wherein the device may be easily applied to or removed from a highway truck.

A still further object 'of the invention is .to provide an attachment "in conformity with the foregoing objects, having improved paint spraying mechanism for producing 'a clear painted line of any desired width.

Yet another important object f the invention "consists in providing a road marking apparatus according to the preceding objects which maybe readily collapsed against the body of a truck for easy transportation and convenient storage when not in use.

These, together with various and ancillary objects of the invention which will 'later 'become apparent as the following description proceeds, are attained by this device, a preferred embodiment of which has been illustrated, by way of example only in the accompanying drawings, wherein:

Figure 1 is a perspective view showing the at tachment applied to ,a truck for transportation by and use therewith;

Figure 2 is a diagrammatic rear elevational view showing the device applied {in operative position to the rear of the truck shown in figure ii; Figure 3 is a diagrammatic top plan view of the construction shown in Figures '1 and 2;

Figure 4 is a perspective view ;of a portion ,of the attachment, showing one of the paint striping units; I

Figure 5 is a fragmentary "side elevational ,view of a part of a truck showing the .device applied thereto; and

Figureii is a perspective view of a detail, showing a part of the adjusting means of the mechamsm.

Referring now more specifically to the annexed drawings, wherein like numerals designate similar parts throughout the several views, there is indicated generally as shown in Figure 1, a truck ll] of any suitable construction and which '2 th s in nc is depicte as a onv n ional yp of truck pl yed y't' hi hw y d artmerits of various states.

Conveniently and suitabiy mounted in the 'b'cdy the truck D, i a a ompress 2 and a p t s o n and a tat n tank 14 o su table design. At the rear of the truck is preferably provided a cantilever type "of platform 15 to accom jnodate and-support the operator of th? strip- ,i'ng device.

Suitable conduits, gauges "and control valves are provided for delivering the air and paint the mixing nozzles of the spraying devices, such conduits forming in themselves no part of this invention. 7

As shown best in Figures 2 3 and .6, Ta 1 3.115- ve'rse supportbar of any suitable construction and indicated at 18 is mounted'rearwardly of the rear W eels or the t uc a d sup or d a b brackets 29 from the platform 16 'or any suitable part of the framework of the truck. 'Detachably conmooted to the extremities "of the support member 1-8, are a pair of laterally extending .outriggfers 22 which are pivotally connected thereto as at 24, and are detachably braced from h framework of the truck as "by reinforcing means 2511ctacha'hly fastened as at 28.

"Ihe outriggers .22 are preferably of tubular construction and telescopingly receive extension members 3!! which are slidable therein and are adjustable longitudinally thereof as by wing nut fastening means 32.

Adjacent the outer extremities .of the extens'ion rods are provided forwardly extending, rigidly attached U-sha'ped frames ,34 within which are journaled pneumatically tired wheels 36 for supporting the outer extremities of the Outriggers. This ,construction shown more clearly in Figure 4.

A plurality of paint spraying nozzles are ad.- j'ustaihly mounted upon the support bar 1,8 and the outr'igger extension 30 in lon itudinally spaced position, each of these painting bein p e bly const u ed as indicated in Fisure 4. Each unit compnises spraying nozzles .Q anysu able typeand ms u o and which are adapted o d scharge a ato spray of paint and air under pressure, the construction of this nozzle forming in itself no part of this invention. These spray nozzles are preferably mounted in any suitable manner upon the support rod 18 and the extension rods 30, and are connected by suitable flexible conduits to the source of compressed air and the paint tank.

Disposed slightly below each nozzle and upon shields or paint guards for regulating the width of the stripe which is to be painted upon the surface of a road or the like. For this purpose, a plurality of clamps 40 are slidably received upon the support bar l8 and rod extensions and are secured in longitudinally adjusted position thereon as by set screws 42. Horizontally disposed and forwardly or rearwardly extending support rods 44 are adjustably attached to the clamps as by means of further fastening means 46. The outer extremities of the rods 44 are provided with shields or guards 48 of generally rectangular shape, and which are preferably disposed at an.

acute angle, such as with the surface to be painted, in such position relative to the nozzle 38, as to limit the spreading of the spray therefrom, and thereby confine the spraying paint to a predetermined width upon the surface to be painted. Obviously, the support rods 44 may be rotated or otherwise adjusted in the clamps 40 to vary the distance between their lower extremities, and thereby regulate the width of strip painted upon the highway.

' It will thus be seen that when both of the out- 'riggers are positioned in their operative assembled relation, as shown in Figures 2 and 3, a plu- "rality of stripes for traffic lanes may be painted mounted upon a shaft 52 suitably journaled in the framework of the truck, suitably attached to the shaft 52 is an operating mechanism which may consist of a conventional cam and lever construction, indicated generally at 54, and provided with an arm 56 which is oscillatable by the mechanism 54 and is pivotally connected as at 58 to a drag link 86 whose extremity is pivotally attached as at 62 to a clamp 64 engaging the support bar l8. It will thus be seen that as the wheel is rotated, theoperating mechanism above described will shift the support rod l8 laterally with respect to the truck In, in order to enable the operator to paint stripes of a curved shape or of varying displacement relative to the truck, as desired.

.As will be understood, one or both of the outriggers 22 may be folded up against the side of the truck, as indicated in dotted lines in Figure 2, when the operation of that portion of the device is not desired. This readily facilitates the passage of the truck through cramped spaces, facilitates the movement of the truck in traflic when the devices for painting are not to be employed, and in general renders the attachment more portable in its nature.

From the foregoing, it will be seen that there has been provided a striping attachment for highways or the like, wherein one or a plurality of trafiic stripes may be simultaneously painted while the truck is operated at a relatively high speed, and wherein the bosses may be appropriately positioned upon the roadbed without having a fixed relation to the position of the truck.

Since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to falling within the scope of the appended claims.

Having described the invention what is claimed as new is:

1. In a striping machine of the type described the improvement comprising: a support bar mounted on a truck and adapted to support a striping device, a clamp on said support bar, a drag link pivotally connected to said clamp, an oscillatable arm pivotally connected to said link and adapted to reciprocate said bar with respect to the truck, said striping device including spray means for dispensing a striping material, a pair of guards adjustably mounted on said bar and having edges defining the width of the stripe and positioned on each side of said spray means, and said bar maving means for adjustably securing said guard edges in preselected angular relation to each other and to the surface being striped.

2. A striping machine comprising a support bar, means for mounting said support bar on a truck, a plurality of paint striping units on said bar, each of said units comprising a paint and air mixing nozzle, a pair of guards on opposite sides of each nozzle for regulating the width of the paint spray discharged from each nozzle and means for adjusting the spacing of said guards with respect to each other, comprising pairs of clamps slidable and rotatable upon said bar, an arm on each guard, each arm being rotatably mounted on one of the clamps for rotation about an axis perpendicular to that of the bar, wherein said bar is mounted for longitudinally slidable movement, and means for moving said bar comprising a central shaft, and a connecting link pivotally connected to said bar and shaft.
